Abstract: A process for pretreating a lignocellulosic material is provided. The process comprises mixing the lignocellulosic material and an alkaline aqueous solution, in a solid to liquid weight ratio of equal to or more than 25:75 to equal to or less than 60:40, in a mixer to produce an aqueous slurry and heat-treating the aqueous slurry at a temperature in the range from equal to or more than 50° C. to equal to or less than 200° C. to produce a heat-treated aqueous slurry comprising a pretreated lignocellulosic material. The lignocellulosic material has a lignin content in the range from equal to or more than 10 wt % to equal to or less than 50 wt %, based on the total weight of the lignocellulosic material. The alkaline aqueous solution has a pH of equal to or more than 9.0.

Abstract: A process for preparing glycols from a lignocellulosic solid biomass involves contacting the biomass with an organic solvent comprising a low boiling point alcohol and a pre-treatment acid at a temperature in a range from 80 to 220° C. and a pressure in a range from 1 to 50 bara. The resulting mixture, having less than wt. % water, is separated into a pre-treated solid residue comprising cellulose and a liquid stream comprising dissolved lignin. The pre-treated solid residue is subjected to a hydrogenolysis reaction. generating a glycols stream, a lights stream, comprising a first portion of organic solvent, and a heavies stream. At least part of the liquid stream is separated to produce a second portion of organic solvent and a lignin stream. At least part of the first and second portions of organic solvent is recycled to the contacting step.
